During the journey of cross-platform mobile app development, I came across Golang which is having a GoMobile command line tool which generates language bindings that make it possible to call Go functions from Java and Objective-C. However, there are some restriction on the types used in an exported function/method as documented here: https://godoc.org/golang.org/x/mobile/cmd/gobind#hdr-Type_restrictions
So any idea about the work in progress to support slices of struct (Array of struct) in the data types used in exported functions
